I did my degree in English/French Language/Linguistics back in the '70s, but I only got a middling grade, and I've worked in software development ever since, so I'm really only an expert on English language in the same way any articulate native speaker is.

To save the trouble of repeatedly doing it on individual posts, I'll just say here that I don't come to EL&U looking for arguments. If I come across as contentious that will nearly always be inadvertent carelessness on my part.
